ios::binary: 以二进制方式打开文件,缺省的方式是文本方式。两种方式的区别见前文
ios::in: 文件以输入方式打开
ios::out: 文件以输出方式打开
ios::nocreate: 不建立文件,所以文件不存在时打开失败
ios::noreplace:不覆盖文件,所以打开文件时如果文件存在失败
ios::trunc: 如果文件存在,把文件长度设为0 -Describes the C++ file operations How ios:: app: an additional way to open the file ios:: ate: File opened locate end of file, ios: app will contain this attribute ios:: binary: open the file in binary mode , the default way is to text mode.
